ARTHUR HONORE BRULARD, OF FORT ST. LEON, LOUISIANA.

GCANE-MILL.

$PECIFIGA'1ION forming part of Letters Patent No. 422,289, dated February 25, 1890.

' Application filed October 6, 1889- serial No. 326,106- (No model.)

' declare that the following is a full, clear, and

exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

This invention relates to sugar or cane mills, and has for its object to provide a new and improved regulator for equalizing the pressure on the cane as it passes between the mill-rollers.

The invention also has for s object to pro vide novel meansfor preventing breakage in the mill from overfeeding or from hard foreign substances that may be fed with the cane.

To accomplish these objects my invention involves the novel construction of parts, the

combination or arrangement of devices, and principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in Which- Figure l is a transverse vertical section of a portion of asugar mill, showing my invention applied thereto. Fig. 2 is an end view of the same. Fig.3 is a detail bottom plan view of th epressuremegulating device, showing the king-bolts in section and the millframe in dotted lines, and Fig. 4: is a detail section on a larger scale.

Referring to the drawings, the lettersA indicate the rollers of a sugar-cane mill; B, the mill-frame, comprising housings for kingbolts D and a bed-plate 0, having on its under side the washers E, through which the king bolts pass. The king-bolts connect at their upper ends with the caps L of the up per roller-shaft M, and at their lower ends these bolts are each provided with a slot re ceiving the end portion of a lever F, which at its outer end is fulcrumed at a on the washer E, and at its inner end is pivoted at H between a pair of levers G, which project go beyond such pivot H and engage under or with the washer E. The opposite ends of the levers G connect with vertical rods 1, supporting a weightplatform J, on which a weight K is supported, all in such manner that the weight presses downward the inner ends of the levers F through the medium of the levers G, and thereby draws down the kingbolts D, with the cap-plates L, which thus exert a powerful pressure on the journals of the upper roller-shaft M. This pressure can be varied and regulated by varying the weight on the platform J to suit the conditions required for obtaining uniform results and the best extraction of juice from the cane. This pressure is a constant one, and is the same on the cane whether the feed be small or large, for the downward strain on the top roller-shaft M, produced by the mechanism described, remains always uniform; but also the top roller accommodates itself to the feed passing through sufficiently to give a uniform extraction of juice, while a uniform pressure is exerted on the cane. By the giving way of the top roller the mill is also prevented breaking from any foreign mattersuch as a piece of iron, stone, or wood, or other hard substance-getting into the rollers, which would otherwise cause a breakage when the king bolts are rigidly screwed down.

My device can be applied to any kind of .mill for pressing any other substance than sugarcane.

What I claim, and desire to secure by Letters Patent, is- I ,1. In a cane-mill, the combination, with an upper and lower crushing roll, of verticallymovable king-bolts having bearing upon the caps of the journals supporting the upper roll, levers fulcrumed at their ends upon the frame and engaging the lower ends of said king-bolts, and levers fulcrumed at their ends upon the frame of the mill and having pivotal connection with the power ends of the levers drawing upon the king-bolts, the latter levers being connected with weights, and the entire series of levers being arranged beneath the rolls, substantially as described.

2. In a cane-mill, the combination, with rolls A A, whereof the upper roll is movable toward and from the other, of king-bolts r00 drawing upon the journals of the movable otally-attaohed levers, substantially as deroll, levers fulcruined at their ends upon opscribed. posite sides of the Washer arranged beneath In testimony whereof I have hereunto subthe frame of the mill, said levers being arscribed my name in the presence of two Wit- 5 ranged to pass each other and lie under the nesses.
